Beside the Pinacanauan river in the town of Penablanca Cagayan, the Callao Caves hid a most unexpected wonder. We walked through this grand cave entrance expecting total darkness ,but instead found a quaint little chapel inside completely bathed by natural light. The multi-chambered caverns have natural overhead crevices that allowed the brightness of day into its dark recesses. Our cameras are going to be useful after all.
It felt cold and damp inside, and was pretty dark in several places. The ground was often muddy and sticky, like walking on freshly-dropped poop. There was this stench that suggested large numbers of bats were hanging from above. (A good reason not to open your mouth in awe while admiring the crevices above!)
At the end of the visit, some of us sat down to say a prayer of thanks. There wasn't enough time to explore all the chambers, so I surmised they also prayed that fate bring them back one day. Enjoy.
